How do I find my correct ring size?

1. Measure the inner diameter of a ring

If you already have a well-fitting ring:

• Measure the inner diameter with a ruler.

• Compare the value with our table
  
  
  

2. Measure the circumference of your finger

If you don't have a ring handy:

• Cut a thin strip of paper

• Wrap it around your finger

• Mark the point where the paper meets.

• Measure the length in mm – that's your finger circumference
  
  

3. Find your size in the table

Use the diameter or circumference and choose the appropriate EU or US size.

Tips for the perfect fit

• Measure your fingers in the evening: they are slightly larger then.

• Cold hands → smaller circumference,
  warm hands → larger.

• For wide rings, it's better to choose half a size larger.

• If you are between two sizes:

  → Take the larger one, especially with non-adjustable rings.
